Well Stimulation (PRE15)

  • 22-26 October 20175 daysAbu Dhabi, UAECourse Fee: 4200 USD

Description

This course covers the main aspects of Well Stimulation whose main objective is to repair formation damage in order to restore / increase production.
The course starts by presenting the basic concepts for stimulation job design, execution and follow up.
Discussion is carried out on formation damage and its effect on well performance and projection of acid stimulation treatments.
Focus is given to the main causes of formation damage (damage during drilling, cementing, perforating, producing and working over wells) and how these may be identified.

Course Level: Intermediate
Instructor: Antonio Abreu

Designed for you, if you are...

  • A petroleum or production engineer, a development geologist, reservoir modeller or field engineer who wants to develop your knowledge on these areas
  • A production manager, field manager, drilling manager, etc.

How we build your confidence

You will be focusing on major areas of Acid Stimulation Techniques. The course focuses both on theoretical concepts and practical onsite experience.
Acidizing with Coiled Tubing will be also discussed in detail, due to its importance in acid placement and formation treatments.

The benefits from attending

By the end of the course you will feel confident in your understanding of:

  • The fundamentals of acid stimulation techniques and their implications on production efficiency
  • How to select and design acid systems for Sandstone and Limestone formations in order to remove formation damage and restore and/or improve a well's productivity
